Texas Instruments SN74AUP1T157 Single 2-Input Multiplexer

Texas Instruments SN74AUP1T157 Single 2-Input Multiplexer selects data from two data inputs (A and B) under the control of a common data select input (C). The state of the common data select input determines the particular register from which the data comes. The output (Y) presents the selected data in the true (non-inverted) form. AUP technology is low-power logic technology designed to extend battery life while operating. All input levels accept 1.8V LVCMOS signals while operating from a single 3.3V or 2.5V VCC supply. This product also maintains excellent signal integrity.

The wide VCC range of 2.3V to 3.6V allows switching output levels to connect to external controllers or processors. Schmitt-trigger inputs (ΔVT = 210mV between negative and positive input transitions) offer improved noise immunity during switching transitions, especially useful on analog mixed-mode designs. Schmitt-trigger inputs reject input noise, allow for slow input signal transition, and ensure the integrity of output signals.

Ioff is a feature that allows for powered-down conditions (VCC = 0V) and is important in portable and mobile applications. When VCC = 0V, signals in the range from 0V to 3.6V can be applied to the outputs and inputs of the device. No damage occurs to the device under these conditions. The Texas Instruments SN74AUP1T157 is designed with an optimized current-drive capability of 4mA to reduce overshoot, line reflections, and undershoot caused by high-drive outputs.
